(10., OF NORRISTOWN, PENNSYLVANIA, A CORPORATION OF PENNSYLVANIA FULLFASHIONED KNITTING MACHINE Application filed January 16, 1930. SerialNo. 421,175.

My present invention relates to improvements in full fashioned knittingmachines, and more particularly it relates to an improved mounting forthe knock-over bits.

An object of the invention is the provision of anarrangemcnt whereby thecuts or slots in the bar for receiving and supporting the knock-overbits may be made true and perpendicular in relation to the bar.-

A further object is the provision of a construction enabling the use ofcutters of substantial width for forming the knock-over bit receivingslots, thus avoiding the use of very fine cutters which are liable totip at an 5 angle and produce an angular cut resulting in an imperfectlyset bit.

Another object is to provide a structure having relatively wide slots inthe bar for receiving the knock-over bits, enabling the re-.

moval orcleaning out from said slots of any roughness or fins on thewalls or bottom thereof which may have been left by the cuttingoperation.

A still further object is the provision of knock-over bit receivingslots of such width that each slot is adapted to receive two knockoverbits separated by a spacer member, the entiredseries of knock-over bitsbeing equally space Other objects will appear hereinafter from theaccompanying description, claims, and drawings.

The invention consists in the'feat-ures, the

combination, and the arrangement of parts hereinafter described andparticularly pointed out in the claims.

Referring to the drawings Figure 1 is a partly section view showing across-section of the bar and clamp with the knock-over bitand spacershown in elevation.

Figure 2 is a plan view of Figure 1.

Fi ures 3 and 4 are elevations of the knockover it and spacerrespectively.

Fi ure 5 is a perspective view of the spacer mem er.

In the drawings, 1 represents the bar in which are cut slots or kerfs 2for receivingv the knock-over bits 3, said slots being. of such width,as shown bestin Figure 2, that each slot is adapted to receive aplurality of knock-- over bits. Two knock-over bits 3 are shown hereinone against cash of the opposing walls of the slot 2, and with spacermember 4 therebetween.

The spacer members 4 are provided with vertical projections 4a like theprojections 3a of the knock-overbits 3. These projections are adapted tobe received in a groove 5 extending longitudinally of the bar 1, tomaintain the knock-over bits and spacers in proper position.

According to the present invention the slots 2 are cutby cutters ofsubstantial width (about 30 thousandths of an inch), as distinguishedfrom the very fine cutters (about 4 thousandths of an inch) heretoforeused to cut individual slots each for receiving a single knock-over bit,thus securing freedom from the danger attendant upon theuse of very finecutters of deflecting of the cutter and producing an imperfect orinclined out not truly vertical. The use of the wider cut- 'tersaccording to the present disclosure produces slots of substantial width,ensures greater accuracy and results in the slots having perpendicularand parallel walls. The wide slots also permit of ready cleanin out offins or projections within the slot le t by the cutting.

The spacer members 4 are equal in width to the intact or uncut portionsof the bar between the slots, thus making the series of knock-over bitsspaced apart equally. In other words the slots exceed in width the por-35 tions of the bar between them, by the thickness of the two knock-overbits.

The usual clamp 6 bears at its forward edge upon the knock-over bits andat its rear edge upon the bar 1 at notch 1a, the clamp being adjustablysecured to the bar by means of screw 7 having threaded engagement withsaid bar.

I claim:

1. In combination, knock-over bits, a bar having a series of integralparallel walls forming divisions between spaces at each side thereof,each of the series of spaces having therein a pair of knock-over bits,and stationary spacers inserted between the knock-over 100 bits, and sacing them apart distances equal to the thicliness of the integral wallsagainst which the bits lie.

2. In combination, knock-over hits, a bar having a series of integralparallel walls forming divisions between spaces at each side thereof,each of the series of spaces being of a width to receive at least a pairof knockover bits with spacers between said bits, and stationary spacersinserted between the knock-over bits, and spacing them apart distancesequal to the thickness of the integral walls, said walls segregating thebits with their spacers into groups, with the bits of each group and thegroups themselves being equally spaced apart.

3. In combination, a bar having transversely extending kerfs in itsupper face and a groove extending longitudinally of the bar across andbelow the bottoms of the kerfs and communicating therewith, knock-overbits and spacers inserted between the bits, each of which bits andspacers has a projection on its lower edge extending into saidlongitudinal groove, and a clamping plate secured to the bar and bearingon,the upper edges of the knock-over bits and spacers.

In testimony whereof, I affix my signature.

KENNETH HOWIE.
